Why EFIXLAB?
Specialization in old and new Fanuc platforms
- NC program and parameter backup — before every repair we archive the machining program and CNC parameters (where technically possible). The machine returns ready for production.
- Older Fanuc series (EOL) are our specialty — Fanuc 0, 6, 10, 11, 15, 16 — models officially unsupported by the manufacturer. We have components for their regeneration.
- Priority for stopped machines — CNC machine tool downtime means huge losses. We react immediately to urgent requests.
- Tests on an axis simulator — after repair we verify controllers and servo drives on a functional test bench before return.
- Repair not replacement — we replace only the damaged component, not the whole unit — savings of up to 80% vs. a new Fanuc module.
- 12-month warranty — on every repair, with no hidden conditions.

Dziękujemy! We have received your request — our Fanuc CNC specialist will contact you shortly.Frequently asked questions
Yes — older Fanuc series (0, 6, 10, 11, 15, 16, 18) are our specialty. We have components and know-how for regenerating these systems, which the manufacturer officially no longer supports. Repair is often the only cost-effective option.
Yes — before repair we archive the machining programs and CNC parameters (where technically possible). After repair we reload them so the machine returns to production without reconfiguration.
Diagnostics and quote: 1–2 business days (priority for stopped machines). Repair after approval: usually 5–7 business days (after receiving necessary components). Express mode is faster. As a rule — repair time may be significantly extended depending on component availability and repair complexity. Deadlines are agreed individually with the client.
Yes — we repair αi-SVS, βi-SVS servo amplifiers and Spindle Power Module αi-SP and βi-SP. Scope includes replacement of IGBT, DC-link capacitors, service of control boards and encoders.
We return the module; if repair is declined, we charge a diagnostics fee (300 PLN net). We can advise on replacements or CNC retrofit to a newer Fanuc system.
Other CNC systems and devices
Fanuc CNC System Repair — Controllers, Drives, and Power Supplies
Fanuc CNC systems — including Series 0i, 16i/18i/21i, 30i/31i/32i controllers, along with Alpha and Beta series servo and spindle amplifiers — are the most widely installed CNC platforms in the machine tool industry. From simple 2-axis lathes to complex 5-axis machining centers, Fanuc controls manage the precision motion, spindle speed, tool management, and part program execution that manufacturers depend on daily. CNC system failures directly impact production capacity and delivery schedules.
Common Fanuc CNC failures include servo amplifier power transistor damage, spindle drive IGBT failures, power supply unit (PSU) degradation causing random axis alarms, LCD display failures in control panels (particularly in older 16i/18i/21i units), main CPU board faults, and interface card failures (FSSB, I/O Link, Ethernet, HSSB). Battery-backed SRAM failures cause loss of part programs and parameters. The Alpha series servo amplifiers often develop electrolytic capacitor issues, while older drives may have difficulty sourcing hybrid IC modules.
EFIXLAB provides comprehensive Fanuc CNC electronics repair across all current and legacy platforms. We repair servo and spindle amplifiers at the component level — rebuilding power stages, replacing gate drivers, and restoring control circuitry. CPU board repairs include memory replacement, communication interface restoration, and SRAM battery replacement with parameter backup. Power supply repairs address capacitor aging, switching transistor failures, and output regulation issues.
Fanuc CNC repair is essential for machine tools representing investments of hundreds of thousands of euros — even a single amplifier failure can idle an expensive machining center. Our repair costs typically represent 30–60% of Fanuc OEM replacement pricing, with significantly faster turnaround. For legacy 16i/18i/21i systems where Fanuc parts availability is declining, our repair capability is critical. All Fanuc CNC repairs include comprehensive functional testing and 12-month warranty.
